National Electrical Code Summary: Article 80 -- Administration and Enforcement
Based on the 2017 NEC
by Mark Lamendola
To be able to work effectively with the NEC, you must understand the
philosophy behind it. This is the information NEC Article 80 provides.
NEC Article 80 is new to the Code, beginning with the 2002 revision.
Formerly, the NEC started with Article 90.
80.1 addresses the scope of the NEC, listing the five functions.
In a nutshell, they are:
- Review (of drawings and specifications)
- Implementation (everything from design through maintenance)
80.2 gives definitions related to administration and enforcement.
Do not confuse this with the definitions in Article 100.
80.3, 80.5, and 80.7 are pretty much for the lawyers.
80.9 addresses how the Code applies to:
- New installations
- Existing installations
- Additions, alterations, or repairs
80.11 basically bars new construction from occupancy if there is
a Code violation and grandfathers existing structures under certain
conditions (mostly that there is no hazard to life or property).
80.13 defines who has authority to administer the code and what
that authority entails. With 16 major points, 80.13 covers a lot of
ground. It codifies what was previously "understood."
80.15 lays out the bylaws for an electrical board, which may be
established by any municipality.
80.17 requires the Authority Having Jurisdiction (AHJ) to retain
80.19 addresses permits and approvals, quite extensively.
80.23 provides rules for notices of violations and penalties.
80.25 provides rules for connecting to the electrical supply.
80.27 describes the qualifications for being an electrical
80.29, 80.31, 80.33, and 80.35 are for the lawyers.
How the NEC is arranged
- The first four Chapters of the NEC apply to all installations.
- Article 90 precedes Chapter One, and establishes the authority of the NEC.
- Article 80 follows the body of the NEC; it exists as Annex H. It provides the requirements for administration.
- Chapters 5, 6, and 7 are the "special" chapters, covering special: occupancies, equipment, and conditions (in that order).
- Chapter 8 provides the requirements for communications systems.
- Chapter 9 provides tables.
- The appendices provide mostly reference information.
- Appendix D contains examples that every NEC user should study.
Try your NEC moxy:
- Do you know the difference between bonding and grounding? Hint: Look in the NEC, Article 100.
- Does the NEC refer to grounding incorrectly in any of its articles? Yes! So be careful to apply the Article 100 definitions. Don't ground where you should bond.
- When doing motor load calculations, which Article covers hermetic motors? Answer: While Article 440 covers the application of hermetic motors, it does so only by amending Article 430 because hermetic motors are a special case of motors. For motor load calculations, refer to Article 430.
- Does the NEC provide a voltage drop requirement? Yes! It does so in a special case, which is Article 648 Sensitive Electronic Equipment. But for general applications, it does not provide a requirement; it merely provides a recommendation in a couple of FPNs.

Remember other applicable codes, rules, standards, and references:
- OSHA's electrical worker safety rules.
- IEEE standards.
- NETA standards.
- NFPA standards.
- International Codes (if applicable to the installation).
- State Codes (if the state has them).
- Local ordinances and permit requirements.
- Local fire codes.
- Manufacturer requirements or guidelines.
- Customer security requirements.
- Industry standards.
- Your company's own internal standards, practices, and procedures.
- Engineering drawing notes.
